Texas red harvester ant, also known as the Texas red ant or "pogo" (genus Pogonomyrmex). These industrious ants collect grass seeds and store them in underground granaries. In fact, they have been shown to reduce rodent numbers by competing with them for grass seeds. Pogos are eaten by "horny toads" and are so conspicuous that people usually notice them before getting stung. Fire ants tend to eliminate this native Texan.

Worker ants are 1/4 to 1/2 inch long and red to dark brown. They have squarish heads and no spines on the body. There are 22 species of harvester ants in the United States, 10 of which are found in Texas. Seven of these species are found only in far west Texas.
